It is possible to define an implementation without referring to a
trait. The methods in such an implementation can only be used
statically (as direct calls on the values of the type that the
implementation targets). In such an implementation, the `of` clause is
not given, and the name is mandatory.

limited to nominal types (enums, classes) and the implementation must
appear in the same module or a sub-module as the receiver type.
_When_ a trait is specified, all methods declared as part of the
trait must be present, with matching types and type parameter
